NASA And SpaceX Launch Experimental Spacecraft That Will Collide With An Asteroid —But It’s Not ‘Armageddon’

Posted by in categories: asteroid/comet impacts, existential risks, satellites

NASA on Tuesday night successfully launched its experimental asteroid deflecting spacecraft which is set to smash into an asteroid at 15,000 miles per hour and serve as a test run for countering any future doomsday scenario where a large space rock could end up on a collision course with the Earth.

KEY FACTS The Double Asteroid Redirection Test (DART), developed by NASA and the European Space Agency (ESA) launched from California’s Vandenberg Space Force Base at around 10.20 a.m. local time Tuesday, aboard SpaceX’s reusable Falcon 9 rocket.

Sometime in 2022, the DART spacecraft is expected to smash into the asteroid Dimorphos which orbits a larger satellite called Didymos—neither of which pose a threat to Earth at the moment—with the hope of deflecting its course.

Read our 3 books at.

The Lifeboat Foundation is a nonprofit nongovernmental organization dedicated to encouraging scientific advancements while helping humanity survive existential risks and possible misuse of increasingly powerful technologies, including genetic engineering, nanotechnology, and robotics/AI, as we move towards the Singularity.

Lifeboat Foundation is pursuing a variety of options, including helping to accelerate the development of technologies to defend humanity, such as new methods to combat viruses, effective nanotechnological defensive strategies, and even self-sustaining space colonies in case the other defensive strategies fail.

Calls grow for US to bolster defense against asteroid threat

Posted by in categories: asteroid/comet impacts, existential risks, government, law

Experts are sounding the alarm about the threat of asteroids to life on Earth — and warning that the United States does not have a clear plan to prevent catastrophe.

Though NASA says the odds are literally one in a millennium, no US agency is explicitly responsible if space rocks are headed our way.

“No one is tasked with mitigation,” former Air Force space strategist Peter Garretson, an expert in planetary defense told Politico. “Congress did put in law that the White House identify who should be responsible, but fully four subsequent administrations so far have blown off their request.”

NASA is tracking a 1,000-foot-tall asteroid that’s headed towards Earth

Posted by in categories: asteroid/comet impacts, existential risks

NASA scientists have issued a warning about a “Potentially Hazardous Asteroid” (PHA) that will fly close to earth in mid-December. The asteroid is larger than 90 percent of asteroids, according to Daily Record, but still smaller than some of the larger reported asteroids. Thankfully, the asteroid won’t come close enough to our planet to do any damage. Near passes like these happen somewhat frequently. But the term “near” is relative when you’re talking about the infinite vastness of outer space.

NASA predicts that the massive asteroid will pass by Earth on December 11, just a month and a few days from now. The asteroid has been classified as 4,660 Nereus, and NASA does consider it very hazardous. The organization says that the asteroid is almost three times the size of a football pitch — roughly the size of the Eiffel tower.

To Save Earth, NASA Is Testing Hitting An Asteroid With A Spacecraft

Posted by in categories: asteroid/comet impacts, existential risks, satellites

“We know of no asteroids that are coming in to hit the Earth,” Rivkin emphasizes. DART, he says, is part of a multi-pronged effort to examine the asteroid collision problem. “Asteroid impacts are really the only natural disaster that humanity can see coming years or decades in advance and do anything about.”

NASA calls DART its “First Planetary Defense Test Mission.” Rivkin is the DART investigation team lead at Johns Hopkins University’s Applied Physics Laboratory, which is running the experiment for NASA.

Researchers recreate deep-Earth conditions to see how iron copes with extreme stress

Posted by in categories: asteroid/comet impacts, existential risks

Far below you lies a sphere of solid iron and nickel about as wide as the broadest part of Texas: the Earth’s inner core. The metal at the inner core is under pressure about 360 million times higher than we experience in our everyday lives and temperatures approximately as hot as the Sun’s surface.

Earth’s planetary core is thankfully intact. But in space, similar cores can collide with other objects, causing the crystalline materials of the core to deform rapidly. Some asteroids in our solar system are massive iron objects that scientists suspect are the remnants of planetary cores after catastrophic impacts.

Measuring what happens during the collision of celestial bodies or at the Earth’s core is obviously not very practical. As such, much of our understanding of planetary cores is based on experimental studies of metals at less and pressures. But researchers at the Department of Energy’s SLAC National Accelerator Laboratory have now observed for the first time how iron’s atomic structure deforms to accommodate the stress from the pressures and temperatures that occur just outside of the inner core.

That’s Why We Haven’t Met Any Aliens Yet!

Posted by in categories: alien life, existential risks

Extraterrestrial life refers to life forms that did not originate and are not indigenous to our planet. So this term covers all possible types of life outside the Earth: These can be viruses, but also plant-like life forms. Some go even further: they are looking for creatures that are very similar to humans in their complexity or even surpass them, popularly known as aliens. But if there is extraterrestrial life, why hasn’t anyone heard about it until now? Do so-called aliens even exist? The Fermi Paradox addresses this very question. What approaches there are to this you can find out here!

Asteroid the size of Eiffel Tower heading for Earth in December

Posted by in categories: asteroid/comet impacts, existential risks

Dubbed 4660 Nereus, or 1982 DB, this vaguely egg-shaped asteroid has a size making it taller than the Eiffel Tower and nearly twice as tall as the Washington Monument. It is set to pass by the planet on December 11 at a distance of approximately 3.9 million kilometers and at a speed of 6.578 km/s.

For comparison, the distance between the Earth and the Moon is about a thousandth of that – around 385,000 km. As such, despite being classified as a Potentially Hazardous Asteroid (PHA) due to its size and close proximity to Earth, it seems unlikely to pose a threat to the planet.
